BTS attended the Billboard Music Awards on May 21 in Las Vegas, where they became the first K-pop group to win a trophy at the annual ceremony when they received the fan-voted award for Top Social Artist. The group was nominated along with artists including Justin Bieber (who previously won six years in a row), Selena Gomez, Ariana Grande, and Shawn Mendes.

Shortly after BTS’s win was broadcast on television, BTOB’s Peniel took to Twitter to express his amazement over the event and congratulate the group.

Woke up to eat breakfast, checked my twitter feed and BAM! Huge step for KPop! Don't know any of them personally but CONGRATULATIONS! ?? https://t.co/x0eY8otA8Y

The account of music video production team Lumpens (which has created many of the group’s MVs) tweeted, “I truly congratulate you. Thanks to you, I’ve become a director for a Billboard [Music Award-winning] artist!” The account later tweeted, “The kids’ ‘most beautiful moment in life’ keeps continuing even in reality,” referencing BTS’s hit series of releases entitled “The Most Beautiful Moment in Life.”

Big Hit Entertainment choreographer Son Sung Deuk (who attended the ceremony) and producer Pdogg also retweeted the announcements by the Billboard Music Awards, with Pdogg writing as his caption, “I’m crying.”
